JIACH GAS-PRO Ex SYSTEM
Advanced Gas Detection & Monitoring for Oil & Gas Drilling Operations
Real-Time Hydrocarbon Detection | Drilling Safety | Mud Logging Integration
The JIACH GAS-PRO Ex System, developed by Jiach Energy Solutions Private Limited, India, is an advanced infrared-based gas detection and monitoring system engineered specifically for oil and gas drilling rigs and mud logging units.
Designed using a PLC-based control architecture, the system integrates precision EPC flow control, gas sampling, gas separation, and advanced detection technologies to provide accurate real-time monitoring of gases released from the wellbore during drilling operations.
The system is controlled through a 10-inch colour touch screen HMI, allowing operators to monitor real-time gas concentrations, system parameters, set values, and actual operating values for safe and efficient drilling operations.
The JIACH GAS-PRO Ex System (GasWatch / Gas Chromatography) is an essential component of the Mud Logging and Safety Monitoring System used on drilling rigs.
Key Capabilities
Total Hydrocarbon Detection (THC)
- Measures hydrocarbon gas concentration up to 100% volume in air
• Provides early detection of hydrocarbon influx during drilling
Hydrogen Sulfide Detection (H₂S)
- Detects toxic H₂S gas, a major hazard in drilling operations
• Gas extracted and analysed from drilling mud using a Gas Trap Unit
Hydrocarbon Gas Composition (C1–C5)
The system detects and analyses key hydrocarbon components:
Gas | Formula | Application |
Methane | C1 | Indicates gas-bearing formations |
Ethane | C2 | Hydrocarbon maturity analysis |
Propane | C3 | Reservoir characterization |
Butane | C4 | Formation evaluation |
Pentane | C5 | Advanced gas interpretation |
Real-time C1–C5 analysis assists mud loggers and drilling engineers in formation evaluation and well monitoring.
